Systematic lymph node dissection in lung metastasectomy of renal cell carcinoma: an 18 years of experience.

BACKGROUND: Pulmonary metastasectomy of renal cell carcinomas (RCC) remains controversial. Thoracic lymph node involvement (LNI) is a known prognostic factor. The aim of our analysis is to evaluate whether patients with LNI, and particularly N2 patients, should be excluded from surgical treatment. METHODS: We retrospectively reviewed data from 122 patients who underwent operations at two French thoracic surgery departments between 1993 and 2011 for RCC lung metastases. RESULTS: The population consisted of 38 women and 84 men; the average age at time of metastasectomy was 63.3 years (min: 43, max: 82). LNI was identified as a prognostic factor using univariate and multivariate analysis (median survival: 107 months vs. 37 months, P = 0.003; HR = 0.384 (0.179; 0.825), P = 0.01, respectively). Although differences in survival between metastases at the hilar and mediastinal locations were not significant (median survival: 74 months vs. 32 months, respectively, P = 0.75), length of survival time was associated with disease-free interval less than 12 months (median survival: 23 months vs. 94 months, P < 0.0001; HR = 3.081 (1.193; 7.957), P = 0.02). CONCLUSION: Although LNI has an adverse effect on survival; long-term survival can be achieved in pN+ patients. Consequently, these patients should not be excluded from surgery. Systematic lymphadenectomy should be performed to obtain more accurate staging and to determine appropriate adjuvant treatment.

Fully endoscopic major pulmonary resection for stage I bronchial carcinoma: initial results.

INTRODUCTION: Several case-series studies of major pulmonary resection (MPR) by video-assisted thoracic surgery (VATS) for non-small-cell lung cancer (NSCLC) have been published, but fully endoscopic MPR is still very rarely performed. Our objective here was to report the outcomes in 71 patients recently managed using fully endoscopic MPR for NSCLC. METHODS: From 2007 to 2009, 635 patients with NSCLC underwent MPR (pneumonectomy, lobectomy or segmentectomy). Among them, 71 (11%) had features strongly suggesting clinical stage I NSCLC and were managed by fully endoscopic MPR, with no utility incision. Lobectomy was performed in 63 patients and segmentectomy in eight patients. Conversion to thoracotomy was required in two (2.8%) patients, because of a fused fissure in one and tight pleural adhesions in the other. Radical lymphadenectomy was performed in all patients. RESULTS: Of the 69 patients managed endoscopically, none died and none experienced intraoperative complications. Mean operating time was 226±38 minutes (range, 137-307 minutes) and mean intraoperative blood loss was 111±93mL (range, 0-450mL). The final histological examination showed stage I NSCLC in 52 patients, NSCLC with node involvement in nine patients (pN1 in 6 and pN2 in 3) and other types of malignancies in eight patients. Mean number of nodes removed was 21±8 after right-sided lymphadenectomy and 23±8 after left-sided lymphadenectomy and the mean number of dissected node sites was 3 (range, 2-5). The postoperative morbidity rate was 23%. Mean postoperative hospital stay length was 6.9±2 days (range, 3-12). CONCLUSION: Fully endoscopic MPR is safe and meets the criteria for oncological surgery.

[Primary myxoid mediastinal liposarcoma]. / Liposarcome myxoïde primitif du médiastin.

Mediastinal liposarcomas (LPS) are rare tumours. We report a case of primary myxoid LPS in a 22-year-old woman suffering from cough, dyspnoea on exercise and asthenia for 3 weeks. Thoracic MRI showed a large tumour on the right side. After neoadjuvant chemotherapy, a complete resection was performed, followed by adjuvant thoracic irradiation. Eighteen months after the diagnosis, no sign of recurrence was detected. Mediastinal LPS include a heterogeneous group of bulky tumours, the progression of which depends on the histological type. The prognosis is dominated by the operability of the tumour. Adjuvant therapies are not established.

[Pleuropulmonary involvement leading to bilateral pneumothorax in a patient being treated for rheumatoid arthritis]. / Atteinte pleuropulmonaire conduisant à un pneumothorax bilatéral chez une patiente traitée pour une polyarthrite rhumatoïde.

INTRODUCTION: Rheumatoid arthritis (RA) is a systemic illness where the development of pulmonary nodule has been described in from 4 to 20% of patients. Symptomatic pleural manifestations occur in 3 to 5% of cases. Rarely, pulmonary nodules become necrotic and lead to pleural complications. Bilateral pneumothorax has only rarely been described. CASE REPORT: We report the case of a 64-year-old woman, who had been treated for RA for several years and presented with bilateral pneumothorax secondary to necrobiosis of one or several pulmonary rheumatoid nodules. The management of the pneumothorax was very prolonged and difficult, and despite surgical pleurodesis, the lung did not reexpand fully. Pathological examination of the pleura revealed a noncaseating granulomatous pattern. The diagnosis of a sarcoidosis like disease, possibly induced by anti-TNFα, or of pleural tuberculosis were suggested, but we concluded that the final diagnosis was of pleural rheumatoid involvement. CONCLUSION: Bilateral pneumothorax secondary to rheumatoid nodule is a rare entity. The management of such a complication is difficult, particularly in patients who receive an immunosuppressant regimen. A granulomatous pattern has been described rarely in the pleural tissue of these patients. Specific RA pleural involvement has to be taken in consideration when other diagnoses are eliminated, especially tuberculosis or sarcoidosis-like disease.

[Totally endoscopic major pulmonary resection for stage I bronchial carcinoma: initial results]. / Résections pulmonaires majeures par voie totalement endoscopique pour carcinome bronchique de stade I: résultats initiaux.

INTRODUCTION: Several series of video-assisted (VATS) major pulmonary resection (MPR) for non small cell bronchial carcinoma (NSCBC) have been published recently. However, totally endoscopic MPR is still very uncommon. We report the initial results of a recent series of 71 patients. METHODS: From 2007 to 2009, 635 patients had a major pulmonary resection (pneumonectomy, lobectomy or segmentectomy) for NSCBC. Seventy-one out of these patients (11%) in whom a clinical stage I NSCBC was strongly suspected were operated on via a totally endoscopic approach, without mini-thoracotomy or utility incision. Sixty-three had a lobectomy and 8 a segmentectomy. There were 2 conversions to thoracotomy (2.8%), for a fused fissure (1 patient) and for tight pleural adhesions (1 patient). The resection was completed by a radical lymphadenectomy in all patients. RESULTS: For the 69 patients who had a totally endoscopic procedure, there was no mortality. No intraoperative complications occurred. The mean duration of operation was 226 minutes + or - 38 (range: 137-307 minutes). The mean intraoperative blood loss was 111 cc + or - 93 (range: 0-450 cc). Final pathological examination confirmed stage I NSCBC in 52 patients while 9 NSCBC were upstaged pN1 (n = 6) or pN2 (n = 3). In 8 cases, another type of malignant tumour was found. The mean number of lymph nodes collected was 21 + or - 8 after right-side lymphadenectomy and 23 + or - 8 after left-side lymphadenectomy and the mean number of dissected lymph node stations was 3 (range:2-5). Postoperative morbidity was 23%. The mean postoperative stay was 6.9 days + or - 2 (range: 3-12 days). CONCLUSIONS: MPR via a totally endoscopic approach is safe and fulfils the criteria for an oncological resection.

[Benign schwannoma with high uptake of 18 fluorodeoxglucose (PET-Scan)]. / Un cas de schwannome bénin avec hypermétabolisme sur la tomoscintigraphie TEP au 18fluorodésoxyglucose.

INTRODUCTION: In patients with a previous history of malignancy, the occurrence of a mediastinal mass with significant uptake of 18 Fluorodeoxyglucose on a PET-scan may lead to biopsy or resection. CASE REPORT: We report the case of a posterior mediastinal mass, with significant uptake of 18 Fluorodeoxyglucose on PET- scan, in a patient with a previous history of testicular seminoma. The lesion was actually a benign schwannoma. CONCLUSIONS: In the case of a mediastinal mass with conventional imaging being in favour of a neurogenic tumour a PET scan cannot confirm benignity or malignancy.

[Full thoracoscopic lobectomy and segmentectomy for benign or metastatic conditions]. / Lobectomies et segmentectomies par thoracoscopie exclusive pour pathologie bénigne ou métastatique.

INTRODUCTION: Several techniques for video-assisted pulmonary lobectomy have been reported. However full thoracoscopic lobectomy, i.e., without the help of a utility incision has seldom been performed. We report our results based on a series of resections for benign or metastatic conditions where mediastinal lymphadenectomy is not indicated. PATIENTS AND METHODS: Fifty-six patients (29 males and 27 females) with a mean age of 46 years (range: 8-82 years) had an attempted major pulmonary resection (54 lobectomies and 2 segmentectomies) via thoracoscopy alone for either a benign lesion (30 cases) or a metastasis (26 cases). RESULTS: There was no operative mortality. Six patients required conversion to thoracotomy (11%). In the 50 remaining patients who underwent an exclusively thoracoscopic operation, there was 1 intra-operative complication that was managed thoracoscopically. The duration of the procedure ranged from 65 to 230 minutes (mean: 157 minutes). Intra-operative blood loss was 55 cc (range: 0 to 200 cc) in the "metastasis group" and 109 cc (range: 0 to 280 cc) in the "benign lesion group". There were 5 postoperative complications (10%). Postoperative duration of stay ranged from 3 to 15 days (Mean: 6.7 days). All patients were seen at the first postoperative month and no clinical or radiological complication was noticed. CONCLUSION: Full thoracoscopic lobectomies are feasible and safe provided appropriate equipment is used and the surgical team is experienced in endoscopic surgery.

[Pleural diffusion of amoxicillin 1 and vancomycin in patients treated for post-surgical empyema]. / Empyème après chirurgie d'exérèse pulmonaire: étude de la diffusion pleurale de l'amoxicilline et de la vancomycine.

INTRODUCTION: Treatment of post surgical thoracic empyema consists of chest tube drainage, antibiotic administration, and in some cases surgical lavage of infected spaces. Data in human on the diffusion of antibiotics in pleural cavity after post surgical empyema are lacking. METHODS: We studied on 9 patients with post surgical thoracic empyema (including 6 pneumonectomy) the diffusion of 2 antibiotics commonly used in this situation: amoxicillin (for 7 patients) and vancomycin (for 2 patients). Antibiotics concentrations were measured after at least 3 days of treatment (3-12 days), in order to reach a plateau concentration in the pleural space. RESULTS: The ratio pleural/plasma antibiotic concentration was 1.96 (range: 0.6-4.9). The pleural infection was cured for 8 on 9 patients. The last patients required thoracostomy, and the outcome was favorable after this procedure. CONCLUSION: That the penetration of amoxicillin and vancomycin in pleural space after post surgical empyema is good. Pleural antibiotics concentrations are in the majority of cases higher than plasmatic concentrations.

[Results of FDG-PET scanning in the pre-operative staging of broncho-pulmonary tumors]. / Résultats de la TEP [18F]-FDG dans la stadification préopératoire des tumeurs pulmonaires.

BACKGROUND: Positron emission tomography (PET) with [18F]fluorodeoxyglucose (FDG) has recently established itself as an important imaging strategy in the management of respectable non-small cell bronchial carcinoma (NSCLC). In this study we report our experience of the impact of FDG-PET in the pre-operative assessment of NSCLC. METHODS: In a single centre retrospective study between 01 January 2000 and 31 Dec 2002, 108 FDGPET scans were performed during the preoperative assessment of histologically proven or strongly suspected NSCLC. RESULTS: The sensitivity, specificity and accuracy of FDG-PET for the characterization of a parenchymatous opacity were 96%, 71% and 92% respectively (4 false negatives, 5 false positives). The sensitivity, specificity and accuracy for mediastinal node involvement were 62%, 94% and 84% respectively (10 false negatives and 4 false positives). The sensitivity, specificity and accuracy for the characterization of adrenal nodules were 88%, 100% and 97% (1 false negative) and for satellite pulmonary nodules 50%, 75% and 64% (2 false negatives and 3 false positives). CONCLUSION: FDG-PET is a useful imaging modality in the pre-operative management of NSCLC but is limited particularly in the characterization of lesions less than 10 mm in diameter and in the evaluation of mediastinal lymph nodes.

Perioperative analysis of biopsies issued from mediastinoscopy.

BACKGROUND: The objective of this study was to evaluate frozen sections of samples obtained at mediastinoscopy for their clinical usefulness. METHODS: This study retrospectively reviewed the records of all patients who underwent mediastinoscopy with perioperative frozen sections in a 1-year period. RESULTS: A total of 123 consecutive patients underwent the procedure. There were no false-positive results. Of the 71 malignant proliferations, 67 were diagnosed from frozen sections. The technique never failed to establish the absence of mediastinal nodal involvement in patients with suspected or proven lung tumors and enlarged nodes (n = 18) who underwent immediate thoracotomy. Frozen sections allowed recognition (n = 36) or strong suspicion (n = 4) of N2 disease in patients subsequently treated by induction chemotherapy. The technique never failed to establish the nonresectability of lung cancer in patients for whom this condition was suspected perioperatively (clinical stage IIIb; n = 10). CONCLUSIONS: Mediastinoscopy with frozen sections remains an extremely useful tool for the management of paratracheal or subcarinal mediastinal disease.

Peroperative frozen section analysis of TTF-1 antigen expression.

BACKGROUND: The assessment of thyroid transcription factor 1 (TTF-1) expression is a useful way to investigate the origin of lung adenocarcinomas or large cell carcinomas when dealing with a solitary lung nodule in a patient with a history of extrathoracic cancer. However, if immunohistological analysis has not been performed before surgery, a peroperative frozen section may be insufficient to distinguish between a primary pulmonary tumour and a metastatic tumour. AIMS: To develop a technique for the rapid assessment of TTF-1 expression that could improve the ability of frozen section peroperative histological diagnosis to answer such questions. METHODS: A rapid immunohistochemical technique (lasting 30 minutes) to assess the expression of TTF-1 was developed and tested. RESULTS: Among the 45 interpretable cases, results of frozen section immunohistochemistry were similar to those found by the standard immunohistochemical technique for the expression of TTF-1. CONCLUSIONS: This technique enables TTF-1 to be analysed peroperatively, but further prospective studies are needed to assess its usefulness in routine practice.

Surgical treatment of lung cancer invading the chest wall: results and prognostic factors.

BACKGROUND: The study was performed to assess prognostic factors in patients with lung cancer invading the chest wall treated by surgery. METHODS: We reviewed retrospectively clinical records of all patients operated on for lung cancer invading chest wall structures between 1984 and 1998. RESULTS: Two hundred one patients were operated on in this 14-year period. One hundred thirty-seven lobectomies, 55 pneumonectomies, and 9 wedge resections were performed. Extrapleural resection (when invasion was limited to the parietal pleura) and chest wall resection (in the case of invasion of deeper structures) were combined with pulmonary resection in 79 (39%) and 122 (61%) cases, respectively. Pathologic TNM stages were T3N0 in 116 (57.5%) cases, T3N1 in 52 (26%), T3N2 in 27 (13.5%), and T4N0-N1 in 6 (3%). A complete resection was achieved in 167 (83%) cases. Fourteen postoperative deaths (7%) occurred. One hundred thirty-nine patients (74%) underwent postoperative radiotherapy. Actuarial 5-year survival was 24% and 13% after complete and incomplete resection, respectively (p < 0.05). Actuarial 5-year survival after complete resection was 25% in T3N0 patients, 20% in T3N1, and 21% in T3N2. In completely resected patients, univariate and multivariate analyses identified three independent prognostic factors: nodal involvement, depth of parietal invasion, and age. Radiation therapy did not improve survival if a complete resection was possible. CONCLUSIONS: Completeness of resection, nodal involvement, depth of invasion, and age affect survival of patients with lung cancer invading the chest wall. N2 disease should not be considered a contraindication to surgery.

Management of empyema complicating lobectomy with superior vena cava replacement.

We present the case of a 49-year-old man with right upper lobe adenocarcinoma invading the right brachiocephalic vein and the origin of the superior vena cava. En bloc resection of right upper lobe with the involved venous segments was carried out through a median sternotomy. Venous pathway was reestablished with a Gore-Tex (W.L. Gore & Assoc, Flagstaff, AZ) prosthesis. Postoperative course was marked by right pneumonia complicated by empyema. The patient underwent thoracotomy with completion pneumonectomy and latissimus dorsi transposition to cover both the prosthesis and the bronchial stump, as well as to fill the cavity. A favorable outcome was observed and long-term survival achieved.

Open window thoracostomy followed by intrathoracic flap transposition in the treatment of empyema complicating pulmonary resection.

OBJECTIVE: Successful treatment of postoperative empyema remains a challenge for thoracic surgeons. We report herein our 12-year experience in the management of this condition by means of open window thoracostomy. METHODS: Open window thoracostomy was used in the treatment of 46 patients with empyema complicating pulmonary resection. A bronchopleural fistula was associated in 39 of 46 cases. Previous operations included pneumonectomy (n = 30), bilobectomy (n = 5), lobectomy (n = 9), and wedge resection (n = 2) performed for benign (n = 10) or malignant (n = 36) disease. In 10 patients open window thoracostomy was definitive because of patient death (n = 2), concomitant major illness (n = 2), tumor recurrence (n = 4), spontaneous closure (n = 1), or patient choice (n = 1). In 36 cases intrathoracic flap transposition was eventually performed. Muscular (n = 29), omental (n = 5), or combined muscular and omental (n = 2) flaps were used to obliterate the thoracostomy cavity and to close a possibly associated bronchopleural fistula. In 9 patients with postpneumonectomy cavities too wide to be filled by the available flaps, a limited thoracoplasty represented an intermediate step. RESULTS: Among patients treated with definitive open window thoracostomy, local control of the infection was achieved in all the survivors (8/8). After open window thoracostomy and subsequent flap transposition, success (definitive closure of the thoracostomy and, if present, of the bronchopleural fistula) was achieved in 27 (75. 0%) of 36 patients. Four initial failures could be salvaged by means of reoperation (initial reopening of thoracostomy and subsequent muscular or omental transposition). CONCLUSION: Open window thoracostomy followed by intrathoracic muscle or omental transposition represents a valid therapeutic option in patients with empyema complicating pulmonary resections.

Aspergilloma: a series of 89 surgical cases.

BACKGROUND: Surgery for pleuropulmonary aspergilloma is reputed to be risky. We reviewed our results, focusing attention on the postoperative complications. METHODS: During a 20-year period, 87 patients were operated on for pulmonary (86) or pleural (3) aspergillomas. Seventy-two percent of patients were complaining of hemoptysis. Eighty-nine resections were performed because there were two bilateral cases. Seventy percent of aspergillomas had developed in cavitation sequelaes from tuberculosis disease. Thirty-four patients had severe respiratory insufficiency that allowed us to perform only lobectomy (18), segmentectomy (2), or cavernostomy (14). RESULTS: Thirty-seven lobectomies (five with associated segmentectomies), two bilobectomies, 21 segmentectomies, 10 pneumonectomies, and 17 cavernostomies were performed. Total blood loss exceeded 1,500 mL in 14 cases, and 71% of patients required blood transfusion. There were five postoperative deaths (5.7%), related to respiratory failure (2), infectious complication (1), pulmonary embolus (1), and cardiorythmic disorder (1). Incomplete reexpansions were frequently seen in patients undergoing lobectomies or segmentectomies. No death or major complications occurred in asymptomatic patients. During follow-up, none of the patients had recurrent hemoptysis. CONCLUSIONS: Surgical resection of aspergilloma is effective in preventing recurrence of hemoptysis. It has low risk in asymptomatic patients and in the absence of underlying pulmonary disease. Incomplete reexpansion is frequent after lobectomy and segmentectomy, especially when there is underlying lung disease. Cavernostomy is an effective treatment in high-risk patients. Long-term prognosis is mainly dependent on the general condition of patients.

Extended resections for bronchogenic carcinoma invading the superior vena cava system.

BACKGROUND: Extended resection of non-small-cell lung cancer (NSCLC) involving the superior vena cava (SVC) system is infrequently performed and oncologic benefits are still uncertain. METHODS: From 1983 to 1996, 25 patients underwent resection of the SVC system for T4, NSCLC. RESULTS: A total of 12 pneumonectomies (48%), ten lobectomies (40%), and three wedge resections (12%) were performed. Seven patients had complete resection of the SVC with graft interposition, 12 patients underwent tangential resection of the SVC, and 1 patient had a pericardial patch; 5 patients underwent resection of right innominate and subclavian veins without vessel reconstruction. The lymph node status was N0 in 8 patients (32%), N1 in 3 (12%) and N2 in 14 patients (56%). Five patients (20%) underwent incomplete resection. Nine patients (36%) developed postoperative complications (36%) that were fatal in 3 patients (12%). At the completion of the study, 10 patients were still alive. The median survival was 11.5 months and the 5-year actuarial survival rate was 29%, with 4 patients alive at 5 years. CONCLUSIONS: The resection of the SVC system for direct involvement by T4, NSCLC can be performed in selected patients with an acceptable postoperative mortality. Even though no significant prognostic factors were observed, the patients who required a lobectomy with limited lymph node involvement seemed to benefit the most from surgery.

Prognostic factors and results after surgical treatment of primary sarcomas of the lung.

BACKGROUND: Primary sarcoma of the lung is a rare tumor. Our purpose was to study survival after resection and prognostic factors, which have been rarely reported. METHODS: In a 24-year period, we performed 20 complete resections and three exploratory thoracotomies only for primary lung sarcomas. One patient declined operation. Mean diameter of resected tumors was 9 cm (range, 4 to 18 cm). There were eight stage IB, eight stage IIB, one stage IIIA, and three stage IIIB. Sixty percent of patients with resected tumors received adjuvant therapy. Age, sex, resectability, tumor size, histologic cell type, stage, and adjuvant therapy were analyzed as predictors of survival. RESULTS: No postoperative deaths occurred. All 4 patients who had no resection died within 15 months. The 5- and 10-year actuarial survival after complete resection was 48%. The 5- and 10-year actuarial survival in stage IB was 83%, whereas the 4-year actuarial survival in stage IIB was 30% (p < 0.05). Complete resection and stage of disease were the sole significant prognostic factors. CONCLUSIONS: Complete resection of primary sarcoma of the lung, when feasible, can achieve prolonged survival, although almost half of the patients died of metastasis within 2 years of operation. Adjuvant therapy needs to be investigated.

[A retrospective study of 53 cases of resectable primary bronchopulmonary cancers associated with Pierre Marie syndrome]. / Etude rétrospective de 53 cancers broncho-pulmonaires primitifs résécables associés à un syndrome de Pierre Marie.

The prognosis of primary lung cancer associated with hypertrophic osteopulmonary arthropathy is not well known. Between July 1973 adn August 1995, we cared for 53 consecutive patients with resectable non-small-cell lung cancer associated with osteoplumonary arthropathy. There were 51 men and 2 women, mean age 56 years. In 83% of the cases the lung cancer was revealed by hypertrophic osteopulmonary arthropathy. The tumor generally involved the right lung (n = 38) and the upper lobe (n = 35). There was no peripheral or central predominance. Complete tumoral resection was performed in 47 patients, incomplete resection in 4 and exploratory thoracotomy in 2. The main histologies were adenocarcinoma (50%) and squamous cell carcinoma (40%). Among the 51 resected tumors, 27 were grade I, 5 grade II, 17 grade III and 2 grave IV. Overall 5-year survival was 39%, reaching 51% for grade I, 40% for grade II, 27% for grade III and 0% for grade IV. The pulmonary manifestations of hypertrophic osteopulmonary arthropathy regressed within the first postoperative hours in all the patients whose tumor was resected and in 1 of the 2 patients who underwent exploratory thoracotomy. AT follow-up, the hypertropic pulmonary arthropathy had disappeared in all resected patients except 1 with a grade I tumor. Tumor recurrence was proven in 18 resected patients, 5 of whom also had recurrent osteopulmonary arthropathy. Our results suggest that primary lung cancer associated with hypertrophic pulmonary arthropathy has characteristic features and that prognosis is comparable with primary lung cancer alone.

Survival and prognostic factors in patients undergoing parenchymal saving bronchoplastic operation for primary lung cancer: a series of 110 consecutive cases.

OBJECTIVE: The purpose of this study was to report our experience concerning bronchial sleeve lobectomy for treating bronchogenic cancer. METHOD: From 1980 to 1994, 110 patients underwent bronchial sleeve lobectomy for bronchogenic cancer. In 45 patients, preoperative investigations contraindicated pneumonectomy, whereas in 65 other patients, sleeve resection was performed without functional necessity. The most common procedures were sleeve lobectomy of the right upper lobe (64%), and of the left upper lobe (21%). Sixteen patients (15%) underwent additional arterial vascular resection. Seven patients had microscopic invasion of the bronchial margin without the possibility of further resection in six with regard to their limited respiratory function. Tumors were staged as follow: 32 stage IB (all T2 N0), 57 stage IIB (57T2 N1), and 17 stage IIIA (eight, T3N1; nine, T2N2), whereas four patients had an in situ cancer (four stage 0). RESULTS: Operative mortality was 2.75%. The 5- and 10-year actuarial survival rates were, respectively, 39 and 22% for the entire group. The 5-year actuarial survival rates were, 60% in stage IB, 30% in stage IIB, and 27% in stage IIIA. Four factors significantly influenced survival (P<0.05): nodal stage, arterial resection, invasion of the bronchial stump and poor functional respiratory status contraindicating pneumonectomy. CONCLUSIONS: In our experience, sleeve resection for stage I provides comparable survival to that of standard resection at equal stage. However, in patients with pathologically N1 disease, who can tolerate a pneumonectomy, a randomized study is mandatory to confirm that sleeve lobectomy can be performed without the risk of decreasing long-term survival. In our study, patients who required an associated vascular resection demonstrated a poor survival.
